Methane reacts with steam to make hydrogen. $\mathrm{CH_4(g) + 2H_2O(g) \rightarrow CO_2(g) + 4H_2(g)}$ . $0.80\,\mathrm{g}$ of methane and $1.35\,\mathrm{g}$ of steam react. One reactant is completely consumed. What volume of hydrogen, measured at room conditions, will be formed?
- A$1.80\,\mathrm{dm^3}$
- B$3.60\,\mathrm{dm^3}$
- C$4.80\,\mathrm{dm^3}$
- D$7.20\,\mathrm{dm^3}$
